Is it okay to treat atheism with good-humoured ridicule on twitter?

If it's funny then maybe, but if you are doing it just to be a jerk then I certainly wouldn't find it funny. But hey, you should expect that from "you know who" -- all he seems to do lately is mock people.

But again, if it's funny then I can laugh at it.

If you're unable to provide a reasoned rebuttal of the atheist position, it may be the best way to divert attention from the weakness of your stance.

You can if you like, but don't expect to get away with it.

Yes, you have a right to free speech

Doesn't bother me ; I make fun of all ethnic groups !

My response would have been that it wouldn't bother me at all...

IMHO

okay enough to know that God doesn't exist

okay enough to make fun of you for not knowing.

Of course. Then await the good humoured replies.

no that would dishonoring to your good to Jesus Christ the one who redeemed you and your salvation depends on it good sir so please don't do that

Pretty sure they can take it.
